Thermal Earth Ltd

Thermal Earth Ltd provides renewable heating solutions from its base in Ammanford, with a particular strength in ground-source heat-pump systems and in-house geothermal borehole drilling. The company says it has operated since 2006 and delivers projects across Wales and the wider UK.

Its drilling team uses three specialist rigs for vertical boreholes, supporting both closed-loop and open-loop configurations. Boreholes can reach up to 180 metres, with loop installation, grouting, testing, header pipework and manifold connections handled as part of the wider installation process. The company also describes methods for difficult ground, including simultaneous drilling and casing.

Projects begin with property assessment, heat-loss calculations, ground surveys and system design. Thermal Earth works on domestic installations as well as larger schemes, including housing developments, social housing, commercial premises, schools, leisure facilities and industrial sites. Shared ground-loop arrays and district-heating solutions are also available for multi-property developments.

Customers can access a complete service covering design, equipment supply, installation, commissioning, monitoring and ongoing maintenance. The business highlights its employed in-house team, remote system monitoring, aftercare plans and support with MCS certification and Boiler Upgrade Scheme applications.

A showroom and training centre in Ammanford provides working heat-pump systems and practical training facilities. The service is aimed at homeowners, developers, building professionals, commercial organisations and heating engineers seeking technically designed, supported renewable-energy systems.
